We’ve been serving Lexington homeowners for over 42 years, from the historic colonials ringing the Battle Green to the garrison colonials and ranches off Waltham Street and Marrett Road. Russell Haines built this company on the idea that a sweep should explain what they found, show you the photos, and give you a plain-English verdict you can act on or set aside. No pressure, no mystery.

Why Hearthstone Chimney Co. Is Lexington’s Preferred Chimney Cleaning & Sweep Company

Lexington homeowners call us back because we document what we find. Every Level 2 inspection ends with dated photos and a written report - not a verbal summary that evaporates once the truck leaves.

Our technicians are background-checked and uniformed, and most jobs finish in one visit. The price we quote is the price on the invoice. We’ve earned a strong local reputation in Middlesex County by showing up when we say and doing the thing correctly.

Dispatch and scheduling are coordinated from our Boston office, but our crews live and work in the Lexington area. We know the difference between a Mass Ave colonial with a 250-year-old central stack and a 1960s ranch with a factory-built fireplace in a prefab chase - and we service both correctly, with the right parts and the right approach.

A live person answers every call, every hour, every day. Not a voicemail, not a callback queue. That’s been true for over 42 years.

Our Chimney Cleaning & Sweep Services in Lexington

Level 1 Inspection

A Level 1 inspection is the annual baseline for any chimney in regular use. We examine the readily accessible portions of the chimney exterior, interior, and connecting appliance - checking for obstructions, combustible deposits, and basic structural soundness. In Lexington’s newer homes, particularly the 1950s-1970s garrison colonials near Waltham Street, this inspection confirms whether your factory-built fireplace and chase cap are still within manufacturer specifications. If we see something that needs a closer look, we’ll tell you plainly and recommend a Level 2 before any work proceeds.

Level 2 Inspection

This is where we get specific. A Level 2 inspection includes everything in Level 1, plus a live camera scan of the flue interior and inspection of attics, crawl spaces, and basements as needed. For Lexington’s factory-built fireplaces - the ones hidden behind chase covers in those postwar ranches and garrison colonials - this is the only way to see cracked refractory panels, warped dampers, or deteriorated DuraFlex liner sections that a visual sweep would miss.

A homeowner near the Minute Man National Historical Park called about smoke smell in a 1960s garrison colonial, and our tech popped the chase cover to find a stamped factory-built fireplace with a DuraFlex liner section and a chase cap that had rusted through at the seam. We pulled the firebox panels, found first-degree creosote flaking off the flue walls and a damper that no longer sealed, then swept the flue, replaced the cap, and documented the firebox for a Level 2 report. Nothing was recommended that we couldn’t show her in the photos.

Creosote Removal

Creosote builds in every wood-burning system, factory-built or masonry. First-degree creosote is flaky and brushes off easily; second-degree is tar-like and requires more aggressive cleaning; third-degree is glazed, hardened, and a genuine fire hazard. Lexington homeowners with newer factory-built fireplaces often assume creosote isn’t a concern because the chimney “looks fine.” It isn’t fine. We’ve pulled chase covers on 30-year-old systems in the Follen Heights area and found third-degree glazing that the homeowner never suspected, because the problem was inside the metal chase, not visible from the living room.

Our sweeps use professional-grade equipment matched to the creosote stage and the flue material. No shortcuts. The flue gets cleaned to NFPA 211 standard, and we show you the after photos.

Soot Removal & Fireplace Cleaning

Soot accumulation isn’t just cosmetic. In factory-built fireplaces, excess soot can degrade gaskets, interfere with damper operation, and reduce efficiency. Our fireplace cleaning service removes soot from the firebox, smoke shelf, and accessible flue areas, then inspects the refractory panels, grate, and hardware for wear. We stock replacement components from Olympia Chimney and Famco for common factory-built models, so most repairs don’t require a second trip.

Trusted Brands We Service in Lexington

We work exclusively with professional-grade materials - no builder-grade substitutes. For Lexington’s factory-built fireplaces and prefabricated chases, we stock and install DuraFlex liner sections, Gelco chase covers and caps, and components from Olympia Chimney and Famco. This matters because a factory-built fireplace is a manufacturer-specific appliance. The wrong cap or an incompatible liner section creates a clearance or draft problem that shows up three winters later as water damage or a smoking fireplace. We match the part to the unit, install it to spec, and document it in your report.

Common Chimney Cleaning & Sweep Problems We See in Lexington Homes

• Factory-built fireplaces neglected because they “look new.” The chase cover hides everything. A clean brick facing in the living room tells you nothing about the rusted cap, cracked refractory panel, or first-degree creosote accumulating inside the metal chase. We find this constantly in Lexington’s 1960s-1970s neighborhoods.
• Sweeps who clean the flue but skip the manufacturer-specific parts. A generic brush job removes loose soot from the flue walls but leaves a warped damper, deteriorated gasket, or cracked panel unaddressed. The fireplace works poorly, smokes occasionally, and the homeowner assumes it’s normal. It isn’t.
• Freeze-thaw damage on thin-wall masonry chimneys mistaken for cosmetic cracking. Lexington sits 11 miles inland, so freeze-thaw cycling is more severe than in Boston proper. Hairline crown cracks on newer thin-wall masonry let water in, which expands when it freezes, which opens the crack further. Left alone, water reaches the flue liner. We’ve replaced crowns on 40-year-old chimneys in the Liberty Heights area that the owner thought just needed caulk.
• Chase caps rusted through at the seam, directing water onto the firebox. Factory-built chase caps are thin-gauge metal with a finite lifespan. When they fail, water runs down the chase interior and pools on the firebox top, accelerating rust and degrading the refractory panels below. We catch this in Level 2 inspections and replace with proper Gelco or Famco caps sized to the chase.
